Websites to make a little extra cash

Just wondering if anyone knows of any websites out there (even similar to mylot) where you can make a little extra cash each month? With the student loans piling up, pretty much all of my income goes to pay those/bills. If I could create a little pocket of spending money from an alternative source that would be wonderful. Any suggestions? Below are the ones I'm currently doing to pay off an up and coming bill:
- Selling textbooks back on Barnes and Noble.com
- Collecting all the loose change around my house to cash in
- Sell old student clarinet
- Sell old prom dresses and any other old stuff i can find lying around
Anything else?

If you're a college student, you probably can write pretty well, right? If you don't mind writing, check out the mylot tasks. If you do some of the "write 4 paragraph" ones for $2 each, they can really add up quickly. It's not going to help you instantly, but it could easily earn $60 a month, for 20 minutes a day.
